IMPROVEMENT IN PROCESSES OF CAPSULING MEDICAMENTS.

Specification forming part of Letters Patent No. 173,226, dated February 8, 1876; application filed September 17, 1875.

have invented a new and useful Improvement in Oapsuling Medicaments of which the'following is a specification: 1

My invention relates to an improved mode of capsuling medicaments by which druggists may furnish them in a neat and readily made up form to the public, to-be taken in an easy and convenient manner; and the invention consists of capsules made of two concaved disks of wafer that are joined by being moistened at the circumference, the cavity of the wafers being filled with the required quantity by means of measuring, moistening, and edge- In the accompanying drawings, Figures 1 i and 2 represent top and sectional side views of a series of concaved disks on which the wafers are placed for receiving the medicaments. Figs. 3 and 4 are, respectively, a side view and central section of the device for moistening the edges of the .top wafers; Fig. 5, a central section of a dish with sponge or similar moisture-retaining fabric-for supplying the moistening device'evenly-with water. Figs. 6 and 7 are, respectively, a sectional-side elevation and end view of the press for connecting the edges of the v'vafers; and Figs. 8, 9, 10, and 11 represent side and top views of the finished capsules in different sizes.

Similar letters of reference indicate corresponding parts.

For the purpose of inclosing' in a neat and secure manner medicaments of all kinds, especially such as are taken'in a pulverized state and in certain fixed quantities, I employ diskshaped Wafers A of different sizes, according to the quantity to be inclosed by the same, and produce them with a concave central part, which may be at the same time'embossed with the name, address, &c., of the druggist, and the name and quantity of the medicament contained therein. The'flat circumferential edges of the disks are connected by being moistened and then compressed in a suitable manner, different devices being used to facilitate and. ex-

A number of concaved stamped wafers are first placed on a series of concaved disks, B, of the same size and shape,--so as to fit exactly thereto, the disks forming the support for the wafers, which are then filled by a graduated measure with the.

exact quantity of the medicament. The outer edges of a corresponding number of wafers are then moistened by the device 0, (shown in Figs. 3 and 4,) which consists of a double metallic tube withinterior filling of suitable fabric that retains and distributes the water, taking it up by dipping it in a 'dish,-D, with spongy material saturated with water. The main object of the dish and moistener is to supply only so much of the moisture as, will be sufficient to produce the adhesion of the edges of the wafers when placed one on the other.

those supplied with the medicaments and transferred with them' to the lever-press E, to-be firmly closed'at the edges. The press E has concaved metal disks, corresponding'in size and shape to the wafers, so that only the edges are compressed while the central part of the wafers is not interfered with.- The jointed wafers form a lens-shaped central space or cavity in which the powders are contained and held securely inclosed by the wafers.

Any medicament taken in the form of a powder may be made up in this manner and kept on hand for any length of time without deterioration. They may be soldinsuitable packages and be taken with the greatest ease,

"without the'slightest disagreeable taste, by

dipping them into water until saturated and swallowing them, together with water, wine,

or other liquid, in the customary manner.

The wafers are readily dissolved by the stomach, and the medicaments thereby quickly Patent 1.
